The specific meaning of the above terms in the present application can be understood in specific cases to those of ordinary skill in the art.

The following is a description of preferred embodiments of the present invention with reference to the accompanying drawings.

The utility model provides a maize picker is received concurrently to high adaptability stem ear, includes the chassis frame, and the chassis frame is including the mount pad 101 that is used for installing the engine, crossbeam 108 before the front side fixedly connected with of mount pad 101, and the rear side fixedly connected with rear beam 1012 of mount pad 101, rear beam 1012 extend backward and constitute the grass collection case supporting part that is used for lifting grass collection case 4, and the upside fixedly connected with of mount pad 101 is used for installing ear of grain case 3 and peeler 11 support frame 102. After adopting above-mentioned structure, the frame is the echelonment, divide two-layer to arrange, the lower floor comprises front beam 108 and rear beam 1012, the upper strata comprises support frame 102, upper mountable ear of grain case 3 and peeler 11, lower floor mountable grass collection case 4, mount pad 101 is the rectangle frame form that the interval set up about two, the maize picker of this frame is adopted, not only can increase grass collection case 4 volume, and compare in traditional maize picker, after grass collection case 4 is fully loaded, 11 centrobaric is low, chassis stability is good, the engine of being convenient for is dismantled the maintenance.

The chassis frame of the existing corn harvester for both stem and ear is of a double-layer beam structure, the grass collecting box 4 is positioned at the rear part of an upper beam and adopts a back-turning or side-turning mode. When the grass is unloaded in the mode of turning back, the large volume of the grass collecting box 4 can be realized, but the grass collecting vehicle must be in a 90-degree state by the harvester, a driver cannot observe the rear part, other people must assist in commanding, and particularly in the process of opening the road, the harvester is required to cut a large empty area so as to ensure that the grass collecting vehicle can be transversely arranged, and the grass is unloaded extremely inconveniently to the vehicle. When the side turning grass discharging is adopted, although a driver can conveniently control the distance of the grass receiving vehicle through the rearview mirror and observe the grass discharging process, the volume of the grass box is smaller, the walking distance is shorter during harvesting operation, grass needs to be frequently discharged, and the operation time of the harvester is seriously occupied.

This scheme has adopted local double-deck roof beam frame structure on prior art basis, and the frame front portion is double-deck roof beam for support other work components. The rear part is of a single-layer beam structure, so that the bottom of the grass box can sink, and the volume of the grass box is increased. The arrangement structure can conveniently unload grains and grass, can realize the configuration of the large grass box, increases the endurance mileage, reduces the grass unloading times, greatly reduces the non-operation time of the harvester, and improves the working efficiency.
